摘　　要：A novel peroxyoxalate chemiluminescence system has been designed for the determination of Triton X-100 （TX-100）, in which a hydrophobic fluorescent conjugated polymer, poly[2,5-bisnonyloxy-1,4-phenyleneethynylene-9,10-anthrylene] （PPEA） was employed as a fluorophor. A strong enhanced intensity of chemiluminescence （CL） was observed in the presence of TX-100, due to the improved emission efficiency of PPEA in the presence of TX-100. Under optimum conditions, the detection range of Triton X-100 is between 1.0 ×10 ^-7 and 1.0 ×10 ^-4 mol·L ^-1, with a detection limit at 6.0×10 ^-8 moloL 1. The relative standard deviation is 2.4% （n=6） for 1.0×10 ^-6 mol·L ^-1Triton X-100. This method provides satisfying results in the detection of TX-100 in nature water and biological samples with high sensitivity and wide linear range.A novel peroxyoxalate chemiluminescence system has been designed for the determination of Triton X-100 （TX-100）, in which a hydrophobic fluorescent conjugated polymer, poly[2,5-bisnonyloxy-1,4-phenyleneethynylene-9,10-anthrylene] （PPEA） was employed as a fluorophor.
